What does PHP or MySQL installation mean?

[lauban]

For buying installation of Xenforo:

• "A XenForo representative will install the latest version on your server, provided it meets the requirements. This does not include PHP or MySQL installation or configuration." What does that last bit about "This does not include PHP or MySQL installation or configuration." mean? Sorry I am not good at technology!
• Also how long would this process take?
  If I bought resource manager would it come preinstalled?

The sever must already have PHP and MySQL software installed and configured, to enable us to install XF.
If you purchase managed hosting, that should be the case.

If you purchase the RM, we will install that also.

Installation time can vary depending on the server but it's usually no more than an hour or two.
